Behind the scene: 3D graphics
Geometry: is defined by XYZ coordinates, size , shape and transformations (scale, rotate, translate)
Properties : the material properties describe how light reflects of off the surface of an object.
Lighting : is the process of determining how much light strikes an object and how much should be reflected.
Shading: determines how the colors are spread accross the surface. The choices are flat shading, in which each facet can be seen to have the same color, and Gouraud shading- smooth shading.
